Ingredients

For the Onion:

2 Large Sweet Onions
2 cups All Purpose Flour
1 teaspoon Cayenne Pepper
2 Tablespoons Paprika
1 Tablespoon Garlic Powder
1 teaspoon Dried Oregano
2 teaspoons Kosher Salt
1 teaspoon Black Pepper
1 cup Whole Milk

Vegetable Oil for frying

For the Sauce:

2 Tablespoons Ketchup
2 Tablespoons Horseradish
½ teaspoon Paprika
⅛ teaspoon Cayenne Pepper
⅛ teaspoon Oregano
¼ teaspoon Salt
½ teaspoon Black Pepper

Instructions

Peel 2 large sweet onions and cut each onion into a bloom shape by making slices from the top down without cutting all the way through the root. Gently separate the onion petals.
In a large bowl, whisk together 2 cups all-purpose flour, 1 teaspoon cayenne pepper, 2 tablespoons paprika, 1 tablespoon garlic powder, 1 teaspoon dried oregano, 2 teaspoons kosher salt, and 1 teaspoon black pepper.
In a separate bowl, whisk together 1 cup whole milk and 2 large eggs until smooth.
Dip each onion into the flour mixture, making sure the coating gets between all the petals. Shake off the excess flour.
Dip the onions into the milk and egg mixture, coating thoroughly. Then dip them back into the flour mixture for a second coating.
Place the coated onions in the refrigerator for 15 to 20 minutes to help the coating set.
Heat vegetable oil in a deep fryer or large heavy pot to 375 degrees Fahrenheit. Carefully lower the onions into the hot oil and fry for 8 to 10 minutes until golden brown and crispy. Remove and drain on paper towels.
In a small bowl, whisk together ½ cup mayonnaise, 2 tablespoons ketchup, 2 tablespoons horseradish, ½ teaspoon paprika, ? teaspoon cayenne pepper, ? teaspoon oregano, ¼ teaspoon salt, and ½ teaspoon black pepper until smooth.
Serve the bloomin onions warm with the dipping sauce on the side.

Notes

It's important to use large Sweet onions for the best flavor of this recipe. To cut the petals of the onions, I find that it's best to make 4 evenly spaced cuts around each of the onions approximately 1/2 inch from the root of the onion making sure to cut down all the way through. Then evenly slice between each section 3-4 times making approximately 12-16 evenly spaced cuts.

When coating the onions, use your fingers to gently separate the onion petals so that each petal gets evenly coated but be careful so that they don't fall off.

Make sure that the oil comes to temperature (375 degrees F) after frying the 1st onion before frying the 2nd onion to ensure that it cooks evenly.

These are best served fresh but you can refrigerate any leftovers in an airtight container for up to 5 days.

Reheat in the air fryer or oven to make the coating crispy again with enjoying the leftovers.
